Universidad de Zaragoza (orcid)0000-0003-0400-8600 Spin Seebeck effect in insulating epitaxial gamma-Fe2O3 thin films 2017 Access copy available to the general public Unrestricted We report the fabrication of high crystal quality epitaxial thin films of maghemite (¿-Fe2O3), a classic ferrimagnetic insulating iron oxide. Spin Seebeck effect (SSE) measurements in ¿-Fe2O3/Pt bilayers as a function of sample preparation conditions and temperature yield a SSE coefficient of 0.5(1) µV/K at room temperature. Dependence on temperature allows us to estimate the magnon diffusion length in maghemite to be in the range of tens of nanometers, in good agreement with that of conducting iron oxide magnetite (Fe3O4), establishing the relevance of spin currents of magnonic origin in magnetic iron oxides. info:eu-repo/grantAgreement/ES/DGA/E26 info:eu-repo/grantAgreement/ES/MEC/FPU14-02456 info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2-R info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2-1-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.127 2017 MATERIALS SCIENCE, MULTIDISCIPLINARY 58 / 283 = 0.205 2017 Q1 T1 PHYSICS, APPLIED 26 / 146 = 0.178 2017 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 37 / 91 = 0.407 2017 Q2 T2 1.63 2017 Materials Science (miscellaneous) 2017 Q1 Engineering (miscellaneous) 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lucas, I.
